Jackson (API)

In computing, Jackson is a high-performance JSON processor for Java. Its developers extol the combination of fast, correct, lightweight, and ergonomic attributes of the library.[1][2]

Implementation

Jackson provides multiple approaches to working with JSON, including using binding annotations on POJO classes for simple use cases.[3][1]

Usage example

Sample code for reading and writing with POJOs may look like the following:[1]

public class ReadWriteJackson {
  public static void main(String[] args) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
   
    String jsonInput = "{\"id\":0,\"firstName\":\"Robin\",\"lastName\":\"Wilson\"}";
    Person q = mapper.readValue(jsonInput, Person.class);
    System.out.println("Read and parsed Person from JSON: " + q);
   
    Person p = new Person("Roger", "Rabbit");
    System.out.print("Person object " + p + " as JSON = ");
    mapper.writeValue(System.out, p);
  }
}
gollark: I also wrote a Python heavdrone for real computers.
gollark: Also, since PotatOS appears to have entered disuse the only SPUDNET users are a large group of inevitable heavdrones.
gollark: SPUDNET supports encoding packets as JSON or msgpack. No implementation except my test JS client uses msgpack mode.
gollark: Or base85 probably.
gollark: Base64 would work.
